SPECIFICATION forming part of Letters Patent No. 265,765, dated October10, 1882.

Application filed June 30, 1882. (No model.)

T 0 all whom it may concern:

Be it known that I, JAMES H. DLAMATTER, a citizen of the United States,residing at Earlville, in the county of La Salle and State ot' Illinois,have invented certain new and useful Improvements in Gultivators; and Ido hereby declare the following to be a full, clear, and exactdescription ot' the invention, reference being had to the accompanyingdrawings, which form part of this speciticatio11,in which- Figure l is aperspective view, and Fig. 2 a side view, of a cultivator embodyingmyimprovements.

This invention has relation to cultivators of that class in which themain frame is composed chiefly of two bars united attheir forward endsand diverging toward their rear ends.

The improvement consists in the novel construction and arrangement otparts.

Referring to the accompanying drawings, A A designate the two divergingbars which constitnte the principal portion ot' the coltivatorframe..These bars are connected attheir `forward ends by atransverse bolt, B,which passes also through the tongue or draft-beam B', embraced by thebars A A. This bolt serves also as a pivot upon which the bars A A andbeam B turn for the purposes of adjustment. The beam li' extendsrearward and upward, and has attached to it the handles C C. Across-bar, D, is secured to the beam B' at its rear end and lholdsstandards b b, which supl port and brace the handles. From the underside ot' the cross-bar D diagonalbraces Zi' b' pass to the bars A A andform a connection between the draftbeam and frame atV their rear ends.

E is a transverse bar, connecting the bars AA behind and underneath thebeam B', and attached to the latter by a vertical pin, e.

--The bars A A have several holes` each, as

seen at c', for the reception of the pins c2 c2, which secure the bar Eto bars AA at dierent points. The bar E is adjustable, and when movedtoward the front or rear of the frame causes or allows the beamyB' to beraised or lowered and the frame A A to be lowered or raised, accordingto the nature of the adjust- Inent. The relative adjustment of the frameand draft-beam requires a corresponding adjustment of the braces b' b',and to effect this the crossbar D is pierced 'in several places,

as shown at d d, for the reception of the bolts or pins which connectthe bar and` braces together.

F F' represent the cultivator-shares. These are made in the form ofblades with 'parallel edges, or with the upper and lower edges oftherear set converging slightly1 toward their rear ends. The ends of theseshares are cut olf obliquely, producing points to enter the earth. Theshares arein two or more sets, in accordance with the usual arrangement.Those in each set converge toward their rear ends, which are higher thantheir forward ends, and are set at an inclination outward from theirlower edges.

This arrangement allows the shares to work the soil easily and properlywithout extraordinary strain or roughness.

G G' arethe sharestandards, pvoted tothe bars A A on opposite sidesrespectively.

g g are braces extending from the lower part of each standard to theopposite side of the bar A to which said standard is attached.

g2 g2 are braces connecting the points of the share and the lowerportions ot' the standard.

H H' are braces, bifurcated at their rear ends, where theyare attachedto the standards, and thence extending forward and adjustably fastenedto the bars A A. The braces H g are fastened io the bars A by the samepins. The standards are made ot"V flat iron, which is twisted to givethe shares the proper obliquity and inclination. The shares are adjustedto regulate their' pitch, &c., by moving the braces H H' lengthwise.

Having described my invention, I claim as new and desire to secure byLetters Patent- 1. The combination of the frame A and inclined centraldraft-beam,B', pivoted together and relatively adjustable with thecross'bar D and supporting standards or braces b' b', substantially asdescribed and shown.

2. The movable and adjustable cross-bar E and braces b' b', incombination with the connected and relatively-adj ustableframeAA anddraft-beam B', substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this22d day of June, 1882. Y
